The author's intention is to "introduce a text a t the undergraduate level while retaining the rigor of Hatsopoulos' and Keenan's presentation" which "demands a level of sophistication generally higher than that possessed by undergraduate students." By presenting a generalized, unified approach to thermodynamics, both texts are intended for students of physics, chemistry, and engineering. Unlike the Hatsopoulos and Keenan (HK) text, the material here could becavered in one semester. Chapter 1,"Fundamental Concepts," hegins with definitions of systems, snrroundings, paths, and properties. In discussing work the author states that the convention of taking work done by the system to be positive "is now universal." Alas, if only this were true. Four new texts on physical chemistry alone use the oooosite convention. Althoueh the drawing of the apparatus nor literature reference thereto is given. Heat and work are correctly described as boundary interactions, hut immediately after stating that they are not forms of energy the (SI) units are given as joules. Adiabatic and diathermal walls are defined in a brief discussion of bringingsystems into equilibrium. Expansion work by the ideal gas is covered in an example. The symbols for C,/C,, heat "flow"and mass are introduced without definition. None of the

In Chapter 2, "Basic Postulates in Classical Thermodynamics and Their Consequences," the author's statement of the first law is that over a cycle Q = W for a system. The law of energy conservation then follows from this. The discussion is brief but clear. considerine lhnt m >ex;mplei o r illuatratirm are ared. The w n p < an I,? said 4 the development of the srrtmd Inrv.Thiilendinnturally t u a d i i cussion of temperature scales in which the Ramsey scale is mentioned, but there is nothing in the text as to the nature of this scale. A brief discussion of thermometry fallows, also devoid of data, illustrations, or references. The discussion an entropy is goad up to the encounter with absolute values a t which point the reader is left to wonder what sort af system might have zero entropy a t absolute zero. Ta begin Chapter 3, "Thermodynamics of One Component Systems," the state functions are derived for a simde svstem. The lirst of the two captioned figures in the entire text appears here, but no reference is made to it in the text nor is there an explanation of the labels used in the figure. It appears that the relevant discussion was omitted. A numher of Maxwell's relations are derived, some of which are used in Chapter 7. The Clausius and Clausius-Clapeyron equations are derived and applications are mentioned. Following very closely the treatment by HK, the first law is nicelygenerdized to cover w e n systems in Chapter 4, "Extension to Flow Processes: Thermodynamics of Open Systems." In deriving equations appropriate to steady flow conditions the author switches to Newtonian fluxion notation, e.g., for dmldt, without explanation or definition of

the symbols. Application of the second law to open systems also closely follows HK even to the point of introducing a function a, the meaning of which is clearly defined by HK but can only he inferred by the reader of this text. The usual expresiions for the temperature .md ur preriure dependence of intrmal m ergy, enthalpy, and entropy are derived in succinct fashion for the ideal gas and extended in less than a page to real gases. Thus begins Chapter 5, "Properties of Ideal Substances." The extension to the ideal liquid and solid. defined as beine incomoressible. is hrirf and to the p i n t . 1.nir 12 n disruii~onof tatdrr oi the thermodynamic pn.pertles of saturated steam, although none are given nor are sources mentioned. Temperature-entropy and pressure-enthalpy diagrams are discussed in the examples. Chapter 6, "Direct and Reversed Heat Engines," appropriately begins with comments on the thermodynamic diagrams, illustrated with p-V and T-S diagrams, each of which shows only the liquid-vapor coexistence "dame." That this is the ease is very difficult to ascertain, especially for the p-V diagram, since coexistence domes are not discussed until the next chapter. The section "Vapor Power Cycles" covers the Carnot and Rankine cycles and their efficiency limitations from practical and theoretical viewpoints. Other cycles of interest, including the Otto, Diesel, and Brayton cycles are similarly treated in the following section, "Gas Power Cycles." Vapor and gas refrigeration cycles conclude this, the longest (49 pp.) and most profusely illustrated (39 figs.), chapter. A one component phase diagram is the hasis for introducing Chapter 7, "Properties of Real Substanees."It is not mentioned that since d p l d T < 0 for the solid-liquid eqnilibrium line the diagram is characteristic of very few substances, e.g. HzO. Following a discussion of state equations for dense gases and the law of corresponding states is a useful section on "Developing Thermodynamic Properties from Experimental Data." After treating the Phase Rule and partial molal properties, equilibrium in terms of chemical potentials is discussed in Chapter 8, "Thermodynamics of Multi component (Continued on page A286)

Systems." Following this are derivations of the temperature and pressure dependences of fugacity and a description of a method of obtaining fugacity values from compressibility data fnr gases. In order to avoid problems when dealing with non-ideal vapors, the ideal solution is defined in Chapter 9, "Properties of Ideal Solutions," as a solution in which each constituent's partial mold volume is the same as its molar volume a t the same temperature and pressure. The other properties of the ideal solution are then derived. Raoult's law and, ultimately, Henry's law appear as consequences of the above definition of the ideal solution and of ideal behavior by the vapor. Boiling point elevation and osmotic pressure equations are then derived. Freezing point depression is ignored. In dealing with nonideal behavior in both vapor and condensed phase solutions, the author uses the expressions "solutions involving coexisting phases" and "two phase solutions" whieh are very confusing since a solution is a single phase. Actlvity and the activity coefficient are covered in a page and a half. No indication is given as t o how activity may he measured.

This annual publication lists currently available free films, filmstrips, slides, transparencies, audiotapes, videotapes, scripts, transcriptions, and printed science materials. More than half of the 1658 items are films and a third are printed materials. All items are fully annotated and eross-indexed according to title, subject, source, and availability. There are, in addition, source and availability indices for Australia and Canada. Although the largest source is the federal government, there are hundreds of other sources. such as universities. industrv. .. and state governments. In addition to the annotated lists of materials, there are instructions and suggestions regarding ordering, a philosophical essay entitled "Children Learning Science" by Professor dahn W. Renner, and eight teacher-prepared units of study which show how the materialscan besuccessfully used a t the elementary, junior, and senior high school levels. As might he expected, most of the materials appear to he designed for use a t the elementary and secondary school levels, with perhaps a fourth of the items suitable for college students. It seems to me that elementsryand secondary school libraries definitely should subscribe to this Guide. At the universitv level. lecture demonstrators in

structional equipment, animal care, greenhouse management, laboratory solutions, electronics, hand tools, and power tools. Vendors of specific laboratory equipment are also mentioned. Unfortunately, because the author is British, most are in England. The sixty-page chapter on laboratory solutions is the longest in the 248~pagebook. Recipes are included for buffer solutions, indicators, analytical solutions, and often used chemistry, biochemistry, and biology solutiuns. Of the four solutions, this general chemistry instructor recently prepared, only one had a reported recipe. Subjects are discussed a t a hasic level; depth and detail are absent. Specialized chemistry handbooks are not replaced by this reference. Untrained laboratory assistants, skilled technicians, and profe&ional scientists are the author's expected users of this manual. The book would verv heloful for scientists educated in one discipline and working in other disciplines. Scientists educated and working in the same discipline would better use the specialized handbooks from their particular disciplines.

In the first two chapters, the author presents an interesting history of the earliest measurements followed by the English system nf measurement. The number of problems or exercises included is far more than necessary to justify going to the metric system. There are almost no examples illustrating how these problems are salved. The last four chapters are devoted t o the metric system using approximately the same format as the first two chapters. Unfortunately, the number of errors in these chapters (including the answers to the problems) increased significantly. Little reference is made to the current metric standards. The gram is incorrectly defined as ".. .the mass occupied Ihy 1 cubic centimeter of water." The day is defined as ". . . the length of time for one revolution of the earth around the sun." Cwwersions within the metric system are dnne exclusively by moving the decimal point, completely neglecting the use of powers af ten. When converting between the metric system and the English system, the use of significant figures was for the most part
